ED,
Darrell,
THIS IS A TEST AS MY PREVIOUS REPLY WAS NEVER POSTED..........
============================================================
The +Famous; TR6 CLUNK in the back is a well known problem at the 6-Pack
forum.
It's the four(4) brackets holding the differential bushings that are cracked
and by the torque, moving forward or backward, is moving a little. The two
metal pieces friction along the crack is making that clunk.
I suggest you have a look at the many postings on several forums to have
access to photos and clear explanation on how to repair. The big three
suppliers are even selling reinforcement for those four brackets to be
welded, +boxing; the supports.
